The vector dominance approach has been successfully applied to different heavy-to-light semileptonic decays, such as
\(B\rightarrow \rho \)  [1]}, \(B\rightarrow \gamma \)  [2]}, \(B\rightarrow K_{1}\)[3]} and \(B_{c}\rightarrow D_{s}^{\ast }\)  [4]}.
The main purpose here is to apply the same technique to \(B \rightarrow K^*(\phi )\)  decays, where we relate the form various factors
of the transition in a model-independent way via Ward identities. This allows us to make a clear separation between
pole and non-pole type contributions [5]}, [6]}. The residue of the pole is then determined in a self-consistent
manner in terms of \(\xi _{\perp }(0)\)  or \(g_{+}(0)\)  which in turn defines the couplings of vector and axialvector
\(B\)  mesons in the \(B \rightarrow V\)  channel. The form factors in the \(q^2\rightarrow 0\)  limit are expressed in terms
of a universal function, \(\xi _{\perp }(0)\equiv g_{+}(0)\) , that is introduced in Large Energy Effective Theory (LEET)  [5]}, [6]}
of heavy-to-light form factors, and the masses of the particles. The value of \(g_{+}(0)\)  will be extracted from the experimental
values of the branching ratios of corresponding \(B_{d,s} \rightarrow V \gamma \)  decays. Eventually, using the above form factors,
we compute branching ratios and compare them with their experimental values in Eqs. (REF ) and () as well
as with the predictions of the LCSR, Lattice QCD and DSE approaches.
